Description
Technical field
The present invention relates to a kind of construction equipment and application process; Specifically; Relate to a kind of bituminous mixture laying equipment and application process of protecting tack coat, this equipment and application process can be applied to the paving of adhesive linkage and bituminous mixture on bridge floor, tunnel or the road surface.
Background technology
The following seal of asphalt highway, tack coat, the water-proof tack coat of deck paving are the important component parts in the asphalt pavement structure.They make cooperative bearing between each layer of flexible pavement for the globality that guarantees asphalt pavement structure, avoid road structure stress under the vehicular load effect to concentrate to produce to damage in early days and have important function.In addition, following seal and tack coat also can play the enclosed construction layer, avoid surface water to pass through the road surface mixture gap and get into road structure inside, cause the bad serious consequence of damage by water.In present construction, the spreading of following seal and tack coat is sprayed by special distribution vehicle to be accomplished, and then carries out the upper strata bituminous mixture laying.Because step-by-step construction, bituminous mixture transport vehicle tire and paver crawler belt can tear seal or bonding layer material, sticking from the scope of operation, the destruction of causing scope of operation seal or tack coat.Even for seal or the not ruined part of tack coat, the dust that the transport vehicle tire carries also adheres on seal or the tack coat easily, causes the pollution of scope of operation tack coat.
Because current deck paving water-proof tack coat, tunnel pavement tack coat and paving tack coat adopt mulseal, bi tumenf orr oad or modified asphalt material more.They have certain infiltration and adhesive attraction to bridge floor, tunnel road surface leveling layer and sub-surface, but still can on the scope of operation, form one deck oil film.This oil film is easy to torn, adhere to by tire under the heavy burden effect and crawler belt, and along with the rolling separating operation face of tire and crawler belt, causes the damage of tack coat, perhaps because dust, clod on the wheel adhere to tack coat, causes the pollution of tack coat.At first; The tack coat that damages or polluted can't play with on cover the effect that bituminous mixture effectively is bonded in the scope of operation; Reduced the globality between pavement structure and following bearing structure or two the bituminous mixture layers, under the pressure at right angle effect of vehicular load, high temperature season particularly; Bituminous mixtures for pavement surface is because the constraint of no bottom adhesive power is easy to occur level to flowing; The rut disease occurs, and the blacktop compound is easy to occur passing, gathering around the bag disease under the horizontal force of vehicular load, reduces the using character and the application life on road surface; Secondly; Because tack coat is destroyed, and has reduced the water resistance of road structure, it is inner that road table water is easy to get into road structure through the space in the bituminous mixture; Under the vehicular load effect, get into the inner water of road structure and become power water; Wash away sub-surface, go up purt behind the formation mud and form purt slurry disease, and under the vehicular load repeat function, cause diseases such as pavement crack, be full of cracks, depression, hole groove then; Simultaneously, glued the bonding layer material that leaves and to be utilized again, also caused waste.
The destruction of flexible pavement tack coat is the technical barrier that always perplexs highway construction circle; Someone attempts adopting rubble insulation blocking tack coat, but has little effect, particularly low temperature season; Because the instability of rubble, the outer effect rubble even become the main cause of destroying tack coat down that carries.
